Background
The regenerated cellulose fiber textile has the advantages of good moisture absorption and air permeability, softness and comfort, good spinnability of the material and the like, and various functional substances can be added into the spinning solution very conveniently in the manufacturing process to manufacture differentiated products, so that the application range is wide. The new coronary pneumonia epidemic situation in this year has certain influence on the market demand trend, antibacterial products become hot spots of market attention, and the comfort becomes an important index of a part of civil antibacterial textiles under the trends of consumption upgrade and market demand subdivision.
The product quality requirements and technical measures of each process are organic integers which are mutually related and influence promotion and conversion, so that the measures are considered and coordinated. Aiming at the development of various series of products of the antibacterial regenerated cellulose fiber home textile, enterprises take corresponding technical measures in various links. The main technical measure of the spinning link is to develop a high count yarn spinning technology and optimize each process by combining the characteristics of the fiber. The weaving link is mainly characterized in that the starting efficiency and the starting quality of high-count varieties are ensured by optimizing drafting and warp position lines, replacing rubber temples and other technical measures. The dyeing and finishing process mainly improves the anti-pilling performance by the low tension combined function after finishing.
However, in the antibacterial and antiviral fabric product based on inorganic nano-powder, because the interface compatibility between the nano-inorganic powder and the organic fabric fiber is not good, the product is easy to have uneven dispersion of the nano-inorganic powder in the preparation process, and the nano-inorganic powder and the organic fabric fiber are easy to separate in the actual use process, so that the antibacterial and antiviral performance of the product is obviously reduced; becomes one of the bottleneck problems restricting the development of the antibacterial and antiviral fabric, in particular to the product added with inorganic nano powder.
